Multiple gamepads/input devices

I am wondering if multiple input devices can be used simultaneously... i.e. as in a 2 person NES emulator. I guess thats its... simple question. My guess is no, but I thought I'd ask
Joe Mac

Read the manual or search this forum...
A channel strip listens to exactly ONE keyboard object. Not to a MIDI keyboard, but an object in the workspace.
In the layout mode you can configure a keyboard object to only listen to certain MIDI events. Usually only they events that come from a specific MIDI keyboard (MIDI port and MIDI channel match). You can however e.g. ignore the channel or port for a keyboard object. Then this object might listen to multiple MIDI keyboards.
This is the trick used for the EVB3: one keyboard object that receives MIDI events from several MIDI keyboards.
Your EXS24 is listen to several keyboards, because you selected the EVB3 keyboard object as its input.
I hope this clarifies the "magic" behind the difference of a MIDI keyboard and a keyboard object.
BTW: There is one exception: if you have no keyboard in the workspace at all, the channel strip will still work: they listen to everything. Its like having a keyboard object with MIDI port and channel set to all/all.

How do I set up multiple midi-input devices:WX5 wind & keyboard controllers

Hello,
I'm trying to setup my system to utilize two midi input devices.
1. Novation Controller Keyboard connected through USB
2. WX5 wind controller connected via VL-70 tone module with midi out cable to channel 1 of my Motu midi interface.
As it is currently setup I am able to play both my Wind Controller and MIDI Keyboards fine, but for some reason whenever I finish playing the Wind Controller, the MIDI Keyboard no longer plays sound (it plays midi fine according to the transport, but no sound is created until I load another patch of the EXS).
What am I doing wrong? Should I be switching between inputs in Logic somehow? How can I setup my system to be able to jump back and forth between my midi keyboard and wind controllers? I have done no setup besides cabling the devices in the AudioMidi setup (outside of Logic).
Thank you in advance for any help you can provide!

This is just a guess, but if the last thing your wind controller puts out is a volume message of zero (as I think it would do as you stop playing the last note) then you would need to send a volume message to the sound module to reset it to the desired volume.

Multiple input device recording/mixing help in Audition 5.5

I'm presently evaluating Audition 5.5 and haven't been able to find any information pertaining to what others MUST do everyday.
I'd like to use Audition to record simultaneous tracks from different sources (microphones). I'm using several USB sound card dongles (each with a single 3.5mm stereo microphone input and headphone/speaker output) as quick and convenient method of creating an array of microphone inputs. Each dongle appears as a discrete audio device with a corresponding input and output.
Fine so far.
Where I'm struggling is in trying to map each microphone to discrete mixer channel. I choose Edit->Preferences->Audio Channel Mapping, but it seems that only channels from any one particular sound device may be mapped to mixer channels at any time. If I assign the microphone from sound card A to Track 1, I can't assing the microphone from sound card B to Track 2. When I try, it alters the hardware device selection and negates any prior channels I've mapped that aren't part of the same device. I hope I've explained the situation clearly.
I'd like to map the microphone from sound device (dongle) A to Track 1, the microphone from device B to Track 2, C to 3 and so forth. But I cant' seem to figure out how to make Audition simultaneously recognize more than any one sound device at any particular time.
Is there a way to do what I'm trying to achieve? Does Audition not support simultaneous mixing/recording from multiple hardware devices? If not, do other products exist that DO support the configuration I'm trying to create which I can use as a front-end - to later mix-down in Audition?
I'd greatly appreciate any helpful insight, guidance, suggestions or recommendations.
Thanks!

I'm not having any SYNC problems that I'm aware of...
Of course you're not - that's because the system prevents you having them by limiting the physical sources you can use!
Here is a brief explanation of the sync problem - I hope it makes sense:
When an input device digitises a signal, it has to provide a clock source for its A-D device. Normally this clock is locally derived, and the device outputs a digital stream at that rate. But if you have two devices (let's say that they were two external USB ones) both trying to be the input device, then their clocks won't be synchronised - inevitably. Audition, and all other software come to that, can only record at one rate, and if another device provides an input that isn't exactly at the same rate and phase as the one providing the master clock, then fairly soon, you get to a point where the data being inputted won't coincide with the main clock any more, and a bloody great click occurs. On older systems where you could use multiple devices, some allowed for the clock sources to be externally synchronised, and a lot of pro gear still does - it helps a lot when you are using digital mixers and external digital preamps if you can feed everything from a master clock, rather than daisy-chaining it.
When it comes to ASIO, Steinberg made the relatively easy decision not even to try to implement it for multiple devices. Instead, they suggest that you use a single device which is capable of supporting as many inputs as your PC can manage. As an example of how this works, my MOTU device that I mentioned above has eight analogue inputs, and also an 8-channel ADAT input. So, without too much trouble I can connect an external 8-channel digital preamp to it and have 16 inputs in total. It uses an optical connection for the ADAT, but to use it I either have to provide sync from the MOTU to the preamp, or use the preamp as the sync source for both itself and the MOTU, replacing the internal clock. With the only digital preamp I have it's this latter option that makes sense, as there isn't an easy way to get sync from the MOTU back to the preamp. (I should perhaps explain that the preamp has got a sync input, but the only sync output from the MOTU comes from its ADAT output, and that isn't easy to feed back in).
Yes, until you get used to it the concept of syncing devices takes a bit of getting used to - Steinberg's idea was to keep it as simple as possible, even though on the face of it, it's rather frustrating.

Usb 6009 multiple analog inputs

I am currently attempting to sample two different analog inputs at different sampling rates using a USB 6009. I keep getting the 'resource reserved' error and am wondering if this is not possible using this DAQ. Questions:
1. Does creating two analog input channels on the device cause this error?
2. Is it possible to sample at different rates on channels created in the same task? (i am trying to 'slow down' the second analog input to display switch points to a customer)
3. Running multiple analog inputs using independent timing would be better achieved by switching to a higher end DAQ? If so which would you recommend?
I have attached my vi. Thank you in advance for your help.
I surf therefore I am....

demo_nolvl.vi ‏27 KB

The DAQ boards only have 1 timing clock for the analog inputs/outputs. So you can only have 1 sample rate on a given card. I would recommend just sampling at the highest of the desired rates in a single task.

Remote System Input Device Not Working

Hi,
when i try to connect remote system through RDP, input device (Keyboard & Mouse) in remote system is too slow, it takes more time to respond. Tried to take RDP from different system but same problem.
Looking forward for your response.
Regards
Mohan Rao R

Hi Mohan,
Since the slowness of displaying mouse movement and input from Keyboard does happen to multiple systems, seems like poor performance to me.
You may improve performance by increasing network bandwidth, reducing workload on the Terminal Server, updating video and network card drivers.

Time synchronization problem with "niUSRP EX Rx Multiple Synchronized Inputs.v i " ??

Hello,
I used "niUSRP EX Rx Multiple Synchronized Inputs.vi "( offred by NI) to synchronize 2 USRP in reception (the master connected to laptop via Ethernet and the slave connected to the master via MIMO cable).
I set: master--> RefIn and PpsIn     slave-->Mimo and Mimo.
Problem: Inspite I used identical cables that connect the both devices to the transmitter; the signal received by the master and the signal received by the slave ar'nt synchronized in time because the time lag (delay) is not constant!!!.
Where is the problem?!!
Thank you

Hi,
I used:
transmitter--> Rohde & Shwartz SM300 signal generator.
Receivers--> 2 x USRP N200 (connected with MIMO cable) master--> RefIn and PpsIn     slave-->Mimo and Mimo.
3 identical cables to transmit the signal, connected via Power Splitter/Combiner (Mini-Circuits).
Cable 10MHz connects the master device with the transmitter.
FreqTx=700MHz (sin)           CarrierFreqRx=701MHz --------> so the received signals are a sin of 1MHz (701-700=1MHz).
I have no probleme with phase synchronisation (because both the slave and the master received a sin of 1MHz).
My problem is the time synchronization:
How can I verify if i did the time synchronization?
I must have 2 superposed sin [(ch0 I with ch1 I) (ch0 Q with ch1Q)] ?
I must do Timed commands? if yes! How to do it?
I try to run the example of constellation, then i have message: Find VI Named".........Vi"    I have this problem all the time when I run some examples . I have probleme with setup LabView?!

Boolean values from multiple Digital Inputs

Hi guys,
This should be really basic but I've looked around to find a solution with no succes...
I have a Digital Input device with multiple inputs.
Eg, I'm reading 0-24VDC signals from pushbuttons and limit switches.
I simply would like to be able to assign each input to a boolean variable to use throughout the code.
Example: I've setup the DAQ Assist and get the usual "Data" output. I'm guessing this produces an array of boolean signals.
How do I convert that array into an individual boolean DI signal for each input?
Or better still, is there a VI I should be using that outputs individual signals?
I've also got the same problem for Digital Outputs. I'm guessing I'll be able to apply the same principles to that problem though.
Sorry if this is obvious and thanks for the help,
Joel
Solved!
Go to Solution.

Index Array will break apart an array into individual elements.
Build Array does the reverse taking individual values and build them into an array.
I would recommend looking at the online LabVIEW tutorials

Keyboard? Multiple Midi Inputs? CAD U1 Mic?

Hello (and, HangTime, if you're there, will really appreciate your answer)
Three questions:
1. MBPro with Yamaha E403keyboard -- GB11 records notes played with piano function but does not record background drumbeat from keyboard. Suggestions to get the background also? (Have already installed latest midi driver from Yamaha.)
2. If I acquire an external Mic can GB accept input from it at the same time as the keyboard? (Have multiple USB inputs available on MBPro.)
3. Any feedback on the CAD U1 Mic? Amazon has it at attractive price for a total novice.
Thanks.

I'm having the same issue with a file called IMG_2353.MOV that was imported into iPhoto from my iPhone and also have to manually select the items to import (so the rogue file doesn't error everything out). I've tried using Image Capture to locate/delete the file directly from my iPhone, but even though I can SEE it in Image Capture, I can't delete it or anything. This is VERY frustrating! My friend/Apple guru's only suggestion was to backup my phone then restore it through iTunes. Risky but should do the trick. I'm too scared to try, though!

That works but the the game will not be in full screen, it will have an empty strip at the bottom.
I actually found out what's the problem. I traced the stageWidth and stageHeight during resizing event. I found out that when it first resized, the stage width and height were the size with the notification bar. So when I pass the stage into startling, myStarling = new Starling(Game,stage), the stage is in the wrong size. For some reason, I can only get the correct stage width and height after the third resizing event.
So now I need to restart Starling everytime a resizing event happened. It gives me the right result but I am not sure it is a good idea to do that.
And thanks a lot for your time kglad~I really appriciate your help.

Can I use a MIDI keyboard as an input device for a software instrument?

I have a Casio CTK-2100 that I am currently playing around with in Logic Pro 9. It can record and playback the different instruments fine using MIDI tracks. But I was wondering if it is possible to use the keyboard as an input device for a software instrument instead of the "Step Input Keyboard".
Is it? If so, how do I set it up?

Yes, the terminology can be a bear, many, many years ago when I started using Logic the manuals were written completely by the programmers, while they were quite humorous in places the were also really hard to understand so I learned/realized.. you can't really do anything so wrong it's going to destroy your computer so why not go ahead and experiment. I learned the basics of Logic without a manual, months later when I went back to find some some details I could figure out the manual made a lot more sense.
Logic has been somewhat Appleized but it's not really an Apple program, it was purchased almost as developed as it is now... a lot of the additions a fluff to make it easier to understand for new users while at the same time there are some real improvements.
This is personal opinion: With all of the forums/online tutorials...etc...etc. It seems users are learning (but not understanding) the same things, plus everyone wants to use it right away so nobody takes a deep breath and investigates on their own. Logic is a deep, deep program, while learning don't be afraid to go off on a tangent and explore the program without any other input, it can actually be inspirational. One other thing good about the manual or "Online Help", in looking up a function you will invariably come across a related concept that will provide further insight.
And..... have fun.

How can I remove a Input device from my Mac?

Hello, I would like to know how I can remove a input device from the Sound area in System Preferences. I installed Wiretap Anywhere a sound input program for my Mac and did not realize It was not supported for Moutain Lion. I put the application in the trash and then emptied the trash can. Now whenever I try to start GarageBand or a program like that it crashes my computer. In the Input tab of Sound (System Preferences) It is listed as Wiretap: System Audio.
I would like to remove this from the Input tab so I can use my Mac reguarly. Any Ideas on how to fix it?
Thanks,
Justin

Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
Here are some general guidelines. Suppose you want to remove something called “BrickYourMac.” First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickyourmac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickYourMac.dmg and open it. There may be an application in there such as “Uninstall BrickYourMac.” If not, open “BrickYourMac.pkg” and look for an Uninstall button.
You may have to log out or reboot in order to complete an uninstallation.
If you can’t remove software in any other way, you’ll have to erase your boot volume and perform a clean reinstallation of OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" that purport to remove software.

Synchronizing two counter frequency inputs with multiple analog inputs

Hello all,
I'm fairly new to LabVIEW and I'm trying to collect data from multiple sources with synchronized timing on the acquisition but I'm having trouble figuring it out. My problem is that I've got two counter frequency inputs, one optical tachometer reading one pulse per revolution, and a max machinery flow meter with a k factor of 12000. I can't seem to figure out how to sync the timing with my multiple analog inputs. I've been attempting to get the tachometer to sync with the analog inputs first by following the example linked here. (https://decibel.ni.com/content/docs/DOC-10785) So far each time I run it I either get a timeout error on the DAQmx read or a "Multiple sample clock pulses were detected" error (see attached image). It seems if I slow the sampling rate way down to say 10 hz and ensure that the tachometer signal is over 800-1000 RPM (13-17 Hz) before starting the VI then the program will run without errors until the RPM drops below that threshold then the "Multiple sample clock pulses" error occurs. The code is attached below.
Does anyone know of a more effective way of syncing counter frequency inputs with analog inputs? I'd like to have a VI that can show 0 RPM (and eventually 0 flow as well, but I think I need to figure out the timing of one counter before I add another as it seems I can't have two counters in the same task). Any help on this would be greatly appreciated.

Maybe third times the charm?
So I've finally got a good handle on why the VI is having problems at low RPM though I'm somewhat embarassed how long it took me to do that
Because I have the counter time synced to my Analog input task if it doesn't see at least two pulses between the two clock pulses set by the analog input task I get the -201314 "Multiple sample clock pulses" error. This seems fine at first as it just sets a minimum RPM that I can measure and it's well below the area I'm interested in so no problems there. I tried a simple error handler that would clear the error when it happend assuming the loop would keep iterating until the RPM went above that minimum at which point I would get a signal again. This is not the case, the read function just continues to spit out the -201314 error even after the RPM is back in the readable range. So then I tried adding two case structures so that when the error occured it would stop the task, clear the error, and then start the task again on the next loop iteration (Code Attached). This also doesn't work as the error shows up again on the stop task and then AGAIN on the start task on the next loop iteration. It seems this error is not actually being cleared and once it happens it stays with the task regardless of what the error cluster is carrying.
Anyone have any ideas? The only solution I can think of is to just clear all tasks and recreate them each loop iteration until the RPM is readable again but that strikes me as a horribly clunky solution.

My old Intel-Based iMac is no longer recognizing USB wired input devices; it only recognizes Bluetooth. What happened?

My friend's old Intel-Based iMac is no longer recognizing USB-wired input devices (Kensington TrackBall, Logitech Mouse) plugged into any USB slot at the back of the computer.
They were working before and for many years.
All of a sudden, A pop up window came up. IT said no Bluetooth mice could be found. We don't know what set off that window to pop up and look for a WL mouse. It never has before in the 5 or more years my friend has been using this computer.
I supplied a wireless Apple mouse and his is back running again.
But want to know why his USB-input devices (Except his keyboard) are not being recognized. He would prefer to use his Trackpad (Wired), but can't find anything in SYstem PReferences to allow that. The computer only seems to want a Bluetooth input device.
Anyone have an idea what happened and if this can be reversed?
I think he is still running Mac OS X 10.5.8.

Hi Carol, lets try this...

Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive/devices.
3. leave it for 10 minutes.
4. Connect back up and reboot.
